Barry,
You can use a drift boat very effectively to fish the Mousam, Kennebunkport, and
Scarborough Marsh. Jim Dione at Northeast Angler an Orvis shop in Kennebunkport,
and listed on this site, has done it for years. He will be glad to give you the
put-in sites.
If you need more info on trout fishing, just drop me a line at my email.
